I'm glad to hear this hotel is still consistent with their nice property and great level of service. I had an excellent stay there about 2 years ago, and can't wait to go back as I have a GLON coming up in 2 weeks.
I think Axey was getting this hotel confused with the 'new' Danube Hilton over across the river near the UN area. IIRC it was in fact either a Holiday Inn or a Scandic before it converted to a Hilton within the past year or two.
